ORCHARD-HEATER.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed October 12, 1914. Serial No. 866,408.

To all 'whom it may concern.'

Be it known that I, WILLIAM C. SCHEU, a citizen of the United States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented a new and useful Orchard-Heater, of which the following is a specification.

This invention relates to heaters for protecting orchards from frost, and the main object of the invention is to provide av heater for this purpose with a stack of sulicient height to give perfect combustion and resulting high heat efliciency, but in which the stack is so constructed that it may be collapsed or lowered when not in use.

Another object of the invention is to pro vide means for cleaning the stack in the collapsing operation.

A further object of the invention is to provide means for reducing or adapting the heateropening to enable different .size stacks` -to be fitted thereto.

This application relates to an improvement on the type of orchard heater shown in my application Serial No. 842,361, filed June 2, 1914, which claims certain features herein disclosed. j

The accompanying drawings illustrate the invention, and referring thereto:

Figure 1 is a side elevation, partly broken away, of a heater provided with my improved stack.

and fitting on said collar, and having an upturned flange or portion 7 adapted to fit within the lower end of the stack. In order to provide a tight joint, the engaging flanges 4 and 6 are preferably tapered and flared, respectively, so that they may be forced into tightcontact, making a substantially air tight joint or connection between the stack and the receptacle 1.

-full length position,as shown in Fig. 1. to

Fig. 2 is a vertical section of the stack in collapsed position. Fig. 3 is a v 4 joint with th receptacle 1, so that the re- 'so as to permit of such telescoping. I also prefer to providev means for frictional engagement between the sections, for example, beads 11 formed on the sections near the ends thereof, and adapted to engage one another when the sections are drawn out to retain the partsin such are forcibly collapsed.

The upper stack section 10 is preferably` provided with means, such as a bar or strip 13 extending across the stack, and secured by spot welding or otherwise, to the stack wall, to serve as a handle in raising or lowering the stack. The fuelreceptacle 1 -may be provided with any suitable means indicated at 14, for supplying or admitting air thereto, for supporting combustion or partial combustion. I prefer to also provide the stack with air position until they admission means consisting of openings 16 in the wall of the lowermost section 9, said openings having louvers 17, formed by bending out or bulging out the wall of the stack directly over each opening, to form deflectors whereby the air is directed properly into the opening, and the openings are protected from entrance of water during rainy weather. As so constructed, the lower stack section operates as a combustion chamber, wherein the vapor generated by partial combustion in the receptacle 1, is completely burnt by further Vcombustion with air admitted through the openings 16. In case` very heavy oil is used however, there will, in general, be more or less deposition of carbon on the lower part of the wall of this section, and the above described collapsible construction of the stack has the further advantage, in this connection, that the next'L inner or higher section, in sliding within the lower section when the stack is being collapsed, scrapes and Cleans such deposit off' of the lower section.

Cover 2 is preferably provided with a ange 2 making a substantially airtight 1 Oli -in the cover of therein. lIn order to r4extends over the receptacle cover 2,

cover with means for engaging section 9 by ceptacle and stack are in substantially airtight connection. A suitable cover 20 is provided for covering the stack when not in use, and said cover may also be constructed to cover the Whole heater, as shown in Fig. 3, said cover in 'that case having an apron or frusto-conical extension 21, whicl serves as a means lof protection against the weather. l I also prefer'to provide this stack the stack, so as to enable the stack tobe'raised or extended bysimply lifting the cover.For this purpose the cover 2() may be provided with depending hooks or lugs 22, adapted -to engage under lugs 23 on the'inner section of the stack, so that on lifting the cover, said inner' section ing the cover, the lugs-:22 thereon may then be disengaged from the section, and the cover the stack. As shown inlfig. 4,the cover 20 may be made without the extension aFore- '1 ceptacle, said said. Said Vcover has a handle 20. y

The construction above described enables the stack to be made comparatively high, so as to give a strong draft effect when the heater is in use, While permitting the stack to be made low when the heater is not in use, so that the device is then brought to compact form suitable for storage, and for protection from the weather. In some cases I may fit the sections together in the manner shown in `Fig. 5, the stack then comprising a lower section 9 having perforations 16 for admission of air, and one ormore upper sections 10 fitted to one another and to the frictional slip joints at their ends.y With this construction itis necessary to assemble or separate the sections in putting up or taking the device is therefore less convenient, though lessexpensive than the vpreferred form of the invention shown in Fig. 1. The stack, as shown in Fig. 1, preferably communicatesdirectly with the interior of the receptacle 1, and the air inlet means 14 the receptacle is preferably formed as angopening havingV a valve or closure 14 whereb' the admission of air may be regulated so as to provide for only partial combustion in the receptacle 1, and resulting generation of combustible vapor limit or confine this partial combustion I prefer to provide a wall member 24 within the receptacle, forming a combustion chamber extending beneath the air inlet means 14 and also beneath the stack to any desired extent, that is, either partially or wholly beneath the stack, 'so as to communicate directly with the air admission means and with the stacli, this wall member 24 being perforated as at will also be lifted. By turnlugs 23 on the stack Y then removed from stack mounted on said down the stack, @and 25 for 'communication of liquid and vapor fromy the receptacle to this combustion chamber.

`What I claim is:

' 1. A. stack for orchard heaters, comprising a plurality of sections, of different diameter, telescoping'and nesting on one another, and provided near their ends, with beads, the beads on adjacent.sectionsfrictionally engaging one another extended position. Y

2. In an orchard heater, the combination with the fuel receptacle, and a cover therelfor having an opening and provided with a flange around said opening, of a reducer tting on and secured to said flange and having anupwardly extending flange, an a stack fitting on said upwardly extending flange on the reducer. n

3. In an orchard heater, the combination of a fuel receptacle, a cover therefor, Y a

cover and communieating directly with the interior of'said recover being provided With air admission means, and a wall member within said receptacle, and extending beneath said air admission'means and beneath said stack,rto form a combustionchamber communicating directly with meansV and with the'stack, being perforated at both portions thereof, to establish oommunlcation between the interior of the receptacle and said chamber. l

4. In an orchard heater, the combination with a fuel receptacle and a cover therefor, of a collapsible stack mounted on said cover, and a lcover for said stack provided with means for detachably engaging said stack, to enable the stack vto be lifted by its cover, and to enable the cover to-then be removed said wall member v from the stack.

5. In an orchard heater, the combination with the fuel receptacle and cover therefor, of a collapsiblestack mounted on said cover, and comprising a plurality of sections provided near their ends with beads engaging one another to hold the stack in extended position, and means connecte-d to the uppermost stack section for lifting the stack.

6. In combination with an orchard heater having a fuel receptacle, a cover therefor, and astack mounted on said cover, a protective cover removably mounted onA said stack and having an apron extending over the fuel receptacle and its cover. y

In testimony whereof I have hereunto set my hand, at Los Angeles, California, this 30th day of September, 1914.
